Tools & capabilities

PushNotif Official MCP Server tools 19

  • register_new_accountTwo-step onboarding tool to request a 6-digit email OTP (step 1: omit otp_code) or verify the OTP to create a new PushNotif account with 1,000 free lifetime credits, register the initial website, and return a live API key (step 2: pass otp_code, password, and name). Use this tool only for brand-new user signups; do not use it for existing accounts (use login_existing_account instead) or to add websites to an existing account (use create_app instead). Public endpoint requiring no API key; step 1 is rate-limited to 5 OTPs per 10 minutes per IP (valid 10 minutes), while step 2 irreversibly creates a tenant and ECDSA P-256 VAPID keypair. Returns JSON { ok, step, tenant: { id, name, email, api_key, credits }, app: { id, site_name, site_url, vapid_public_key } }.
  • login_existing_accountAuthenticate an existing PushNotif account using email and password to retrieve its live API key and registered apps, with optional inline profile name or password update (when new_name or new_password is provided). Use this tool for existing users connecting from chat or updating account credentials; do not use it for new signups (use register_new_account instead) or app-level branding (use update_app_branding instead). Requires valid email and password (no prior API key needed), costs 0 credits, and is rate-limited against brute-force attempts; read-only unless new_name or new_password is supplied. Returns JSON { ok, tenant: { id, name, email, api_key, credits }, apps: [{ id, site_name, site_url }], profile_updated }.
  • list_appsList all registered websites and mobile apps in the workspace with active subscriber counts, current credit balance, and optional framework SDK installation snippets (when include_sdk_framework is set). Use this tool first as a prerequisite to obtain a valid app_id before calling send_push_notification, schedule_push_notification, update_app_branding, delete_app, configure_inapp_banner, or configure_rss_autopush; do not use it to inspect individual subscriber devices (use list_subscribers instead). Read-only operation requiring PUSHNOTIF_API_KEY with 0 credit cost; when include_sdk_framework is passed ('html', 'nextjs', 'laravel', 'wordpress', 'flutter'), each app entry also includes ready-to-paste SDK setup code. Returns JSON { tenant_name, credits_balance, total_apps, apps: [{ id, site_name, site_url, active_subscribers, sdk_guide }] }.
  • create_appRegister a new website domain or mobile application under the authenticated workspace and generate its unique ECDSA P-256 VAPID keypair and 1-line HTML SDK snippet. Use this tool when adding an additional website or app to an existing account; do not use it to modify an existing app's icon, welcome push, or mobile keys (use update_app_branding instead) or to remove an app (use delete_app instead). Requires PUSHNOTIF_API_KEY, costs 0 credits, and creates a persistent app record where site_url must be a valid HTTPS origin (or http://localhost for local testing). Returns JSON { ok, app: { id, site_name, site_url, vapid_public_key, created_at }, sdk_snippet }.
  • update_app_brandingUpdate an existing application's notification icon URL, automated welcome push message (including drip delay welcome_delay_sec and promo target URL welcome_url), zero-downtime custom VAPID keys (vapid_public_key & vapid_private_key for migrating from OneSignal/LaraPush), and optional native mobile push credentials (Android FCM HTTP v1 service account JSON and iOS APNs .p8 key). Use this tool to configure app-level branding, onboarding welcome alerts, custom VAPID key migration, or native mobile credentials; do not use it to create a new app (use create_app instead) or configure on-site HTML popups (use configure_inapp_banner instead). Prerequisite: call list_apps first to obtain app_id. Requires PUSHNOTIF_API_KEY and idempotently updates only the fields provided at 0 configuration cost (when welcome_enabled=true, each new subscriber welcome push deducts 1 credit; APNs requires apns_key_id, apns_team_id, apns_bundle_id, and apns_p8_key together). Returns JSON { ok, app_id, icon_url, welcome_enabled, welcome_url, welcome_delay_sec, custom_vapid_updated, android_fcm_configured, ios_apns_configured }.
  • delete_appPermanently delete a registered application (app_id) along with all of its subscriber device tokens, scheduled campaigns, and delivery history. Use this tool only when a user explicitly asks to remove a duplicate or decommissioned app; do not use it to pause notifications or change app settings (use update_app_branding or configure_inapp_banner instead). Prerequisite: call list_apps first to verify the exact app_id and active subscriber count. Requires PUSHNOTIF_API_KEY, costs 0 credits, and is irreversibly destructive (confirm_delete must be set to true or the call is rejected). Returns JSON { ok, deleted_app_id, deleted_site_name, subscribers_removed }.
  • send_push_notificationBroadcast an immediate push notification across Web Push (VAPID), Android (FCM), and iOS (APNs) to active subscribers of a specific app_id. Use this tool for instant real-time delivery; do not use it for future or recurring broadcasts (use schedule_push_notification instead) or on-site HTML popups (use configure_inapp_banner instead). Prerequisite: call list_apps first to obtain app_id. Requires PUSHNOTIF_API_KEY, deducts 1 credit (Rp 0.20) per successfully delivered device (0 credits charged for 404/410 dead tokens, which are auto-pruned), and is irreversible once dispatched; when segment is set to a custom tag (from update_subscriber_tags) instead of 'all', only subscribers carrying that tag receive the broadcast, and omitting url defaults the tap action to the app's registered site_url. Returns JSON { ok, campaign_id, total_targeted, total_delivered, total_gone_pruned, credits_deducted, credits_remaining }.
  • schedule_push_notificationCreate a new scheduled or recurring push notification campaign, edit an existing queued campaign (via update_campaign_id), or cancel a queued campaign before execution (via cancel_campaign_id). Use this tool for delayed, recurring, or editable future broadcasts; do not use it for immediate sending (use send_push_notification instead) or automated RSS feed polling (use configure_rss_autopush instead). Prerequisite: call list_apps to obtain app_id, or call get_campaign_analytics to obtain an existing cmp_sch_xxxx ID for editing or cancellation. Requires PUSHNOTIF_API_KEY; scheduling, editing, or canceling costs 0 credits up front, and 1 credit per delivered device is deducted only when the schedule fires (mutually exclusive modes: pass cancel_campaign_id to delete, update_campaign_id to modify fields in-place, or neither to create a new schedule). Returns JSON { ok, action, scheduled_campaign: { id, app_id, title, body, scheduled_for, recurrence_rule, status } }.
  • configure_inapp_bannerConfigure and publish an on-site In-App Popup or Banner (center modal, top sticky bar, or bottom slide-in toast) rendered inside the website by the PushNotif SDK without requiring browser push permission. Use this tool for visual in-page promos and announcements; do not use it for OS lock-screen notifications (use send_push_notification instead). Prerequisite: call list_apps first to obtain app_id. Requires PUSHNOTIF_API_KEY; saving configuration is idempotent and costs 0 credits, while each live visitor display deducts 1 credit (inapp_trigger controls when the banner fires—such as 'scroll_50' for 50% page scroll or 'event:add_to_cart' for custom DOM events—combined with inapp_freq to cap repeat impressions per visitor). Returns JSON { ok, app_id, inapp_enabled, inapp_style, inapp_trigger, inapp_freq }.
  • configure_rss_autopushConfigure automated 24/7 RSS, Atom, or XML Sitemap polling for an app_id, or trigger an immediate feed check and push broadcast via dispatch_now=true. Use this tool when a blog, news portal, or store wants newly published URLs automatically broadcast as push notifications; do not use it for manual one-off messages (use send_push_notification instead) or fixed-time calendar campaigns (use schedule_push_notification instead). Prerequisite: call list_apps first to obtain app_id. Requires PUSHNOTIF_API_KEY; feed URLs are validated against SSRF rules, deduplicated by item GUID/URL so each post is sent only once, and deduct 1 credit per delivered subscriber when a new item is broadcast (setting dispatch_now=true immediately fetches and broadcasts the newest feed entry even if rss_enabled=false). Returns JSON { ok, app_id, rss_enabled, rss_feed_url, rss_interval, dispatched_now, latest_item_title }.
  • configure_payment_webhookGenerate the ready-to-paste Universal Incoming Webhook URL (POST /api/v1/apps/{app_id}/incoming-event) for 9 auto-detected formats (Midtrans, Xendit, Mayar, Lynk.id, Duitku, Tripay, Supabase Database/Auth, Saweria/Trakteer, Shopify, WooCommerce, GitHub, and Custom JSON), or trigger a live test event when simulate_test=true. Use this tool when connecting a payment gateway, Supabase backend, creator tipping page, or e-commerce store to automatically show a Live Activity Toast, broadcast a Web Push, and/or send a transactional receipt email upon settlement; do not use it for RSS blog feeds (use configure_rss_autopush instead) or manual push campaigns (use send_push_notification instead). Prerequisite: call list_apps first to obtain app_id. Requires PUSHNOTIF_API_KEY; generating the webhook URL costs 0 credits, while live or simulated push broadcasts deduct 1 credit per delivered device (toast_only mode costs 0 credits on display). Returns JSON { ok, app_id, mode, webhook_url, supported_platforms, setup_guides, simulation_result }.
  • list_subscribersRetrieve active subscriber device records, assigned segment tags, platform breakdown counts (Web VAPID, Android FCM, iOS APNs), or full CSV/JSON backup export for zero-downtime migration. Use this tool to inspect audience size, platform distribution, export subscriber tokens (export_format="csv" or "json"), or obtain a subscriber_id before calling update_subscriber_tags; do not use it to view campaign click metrics (use get_campaign_analytics instead) or modify/import subscribers (use update_subscriber_tags instead). Read-only operation requiring PUSHNOTIF_API_KEY with 0 credit cost; filter by app_id and optional tag to narrow results. Returns JSON { total_active, platform_breakdown: { web, android_fcm, ios_apns }, subscribers: [{ id, app_id, platform, tags, created_at }], export_data }.

Substack MCP Server tools 27

  • create_draft_postcreate a draft post on your Substack account.
  • set_post_bodyreplace the body of a draft with a Substack document. This is the only way to write structured content — headings, lists, links, code blocks, images, buttons and a paywall. Create the draft first with create_draft_post, then call this with its id. The result reports how many nodes of each type were stored, so a caller can confirm that what it asked for is there. An image must already be hosted by Substack: this cannot upload one.
  • upload_imageHost an image on your Substack publication and get back a Substack URL — the one thing image2.src in set_post_body and cover_image in update_draft will actually render. The source is either an http(s) URL, which the server downloads and re-hosts, or `path`, an absolute path to a local file on the machine running this server, which is read straight from disk: use that for an image you generated or edited locally, with no need to publish it anywhere first. Private and loopback hosts are refused, HEIC is not accepted, max 10 MB.
  • list_subscribersList and filter the subscribers of your Substack publication. Supports the same 48 columns and operators as the Subscribers dashboard, combined with AND, plus free-text search, sorting and pagination. Returns `count`, the total matching the filters regardless of `limit`, so a call with limit 1 is a cheap way to size a segment. Engagement columns (email opens, post views, comments, shares, activity rating) can be filtered on here but are not part of the records this tool returns — use export_subscribers to read their values.
  • export_subscribersExport subscribers with their full column values, including the engagement metrics list_subscribers can filter on but not return: email opens over 7d/30d/6mo, unique emails seen, post views, unique posts seen, comments, shares, links clicked, days active and activity rating. Takes the same filters as list_subscribers and covers the whole matching set — there is no paging. Substack generates the file asynchronously, so this waits for it and returns the parsed records. One column cannot be exported and is reported in `missing_columns` rather than failing: tag_ids.
  • list_postsList the posts of your Substack publication: drafts, published posts or scheduled posts. Supports free-text search, pagination and sort direction. Each post is returned as a summary; use get_draft for the full content of an unpublished one.
  • get_draftRead one draft post of your Substack publication in full, including its body and its audience and email settings. Take the id from list_posts or create_draft_post.
  • update_draftChange an existing draft's title, subtitle or any of its Post settings: audience, who may comment, comment order, cover image, social preview title and description, SEO title and description, and URL slug. The update is partial: only the fields you pass change, everything else — including the body — is left alone. A cover_image not already hosted by Substack is downloaded and re-hosted first. Take the id from list_posts or create_draft_post.
  • publish_draftPublish a draft. The post goes live on the web; `send` additionally emails it to subscribers and defaults to false, because an email cannot be recalled. Publishing cannot be undone from this server — there is no unpublish tool.
  • delete_draftDelete an unpublished draft. Refuses if the id belongs to a published post: Substack deletes both through the same endpoint, and removing a live post is irreversible, so that is left to the dashboard.
  • get_publicationRead the settings and identity of your Substack publication: name, subdomain, custom domain, hero text, copyright, sender name, logo, plans and payment state. Returns a projection by default; pass full: true for all 111 fields.
  • get_user_profileRead the account behind the session: id, handle, name, bio, and every publication you have a role on. This is how to discover which publications the session can reach, beyond the one SUBSTACK_PUBLICATION_URL points at.
